Title: Improvements in and relating to addition circuits
IPC: G06F7/50
Filed: 1959-08-31
Abstract: 895,251. Decimal addition. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 31, 1959 [Aug. 29, 1958], No. 29689/59. Addition to 884,488. Class 106 (1). The adder of the parent Specification in which delays representative of digits of the addend and augend are imposed on a pulse, the resultant delay representing the sum of the digits, is modified in that each order other than the first of a multi-order adder is provided with a unit delay representing a carry. Addition, utilizing tapped delay lines 21, 28, 38 and 48 and switches 25, 35, 45, 28, 38 and 48, is carried out as described in the parent Specification and pulses appear, delayed times representative of the units order sum on line 30, and of the tens and hundreds orders sums on lines 40 and 50 respectively. Line 40 divides to provide inputs for AND gates 42a and 42b, the line to gate 42b containing a unit delay. The other inputs to the AND gates are lines from units carry trigger 62, a bi-stable device marking line 68 in the normal state and line 69 to gate 42b when triggered. A carry from the units order is produced by an output from AND unit 60 setting trigger 62 to mark line 69 thus opening gate 42b and closing gate 42a. There is an output from AND unit 62 when the pulse on line 30 coincides with a timing pulse produced in the interval 10 to 19 unit delays after the operation started. This arrangement is repeated for simple carries from the tens and hundreds orders but for carries from a higher order due to carry from a lower order a trigger, e.g. 74, is set when the higher order sum is 9 and supplies one input to an AND unit 75, the other input being from the carry trigger if the lower order, and the AND unit output setting the carry trigger of the higher order. As shown the units, tens and hundreds sum lines are connected through a selector switch 64 to line 62, a pulse on this line appearing at one of the AND units 61-0 to 61-19 in coincidence with a timing pulse from the tap of line 21 with which the AND unit is connected. The outputs of the AND units are applied to OR circuits 66-0 to 66-9. In the apparatus shown three pulses are required to complete the three-order addition ; the first sets the carry triggers and indicates the units sum by marking one of the outputs of OR circuits 66, the second and third, after operation of switch 64, indicating the tens and hundreds orders sums.

Title: Improvements in or relating to track apparatus in railway traffic control systems
Inventor: OPITZ WALTER
IPC: B61L3/12
Filed: 1953-10-27
Abstract: 736,940. Railway signaling track apparatus. SIEMENS & HALSKE AKT.-GES. Oct. 27, 1953, No. 29712/53. Class 105. In a railway traffic control system, to avoid faulty operation, e.g. of axlecounting apparatus due to stray influence on the receiver by iron or magnetic parts on the train, the impulses generated in two receivers 2, 5, Fig. 1, as by the wheel 4 of a train are applied to control directly or indirectly two series connected contacts 21, 51, Fig. 2, in the controlling circuit of a relay 7 so that only when the two contacts 51, 21 are closed concurrently can the relay 7 be operated. If the direction of travel is to be indicated and the receivers 2, 5 are consequently staggered in relation to each other, the operation of one of the contacts, say, 51, controlled by the first influenced receiver 5 is either retarded or an auxiliary relay operated by the impulse from receiver 5 and which operates the contact 51 is self-holding until the influence has passed the other receiver 2 to operate the contact 21. The receivers 2, 5 may be disposed on the inner sides of the rails and may be reversed as regards their polarities.

Abstract: 1,152,495. Recording data on pneumatic tyres. UNIROYAL, Inc. 5 July, 1966 [20 Aug., 1965], No. 30132/66. Heading B7C. [Also in Division G4] A digital magnetic code recorded on circumferential magnetizable members, such as bead wires, on axially opposite sides of a tyre carcass is made up of an indexing digit in circumferential alignment on the two members, and information digits relatively angularly displaced on the two members. Apparatus for recording the code comprises a set of magnetizing members arranged circumferentially around each magnetizable member with a magnetizing member of one set in alignment with a magnetizing member of the other set for recording the indexing digit, the other magnetizing members in each set being displaced from those in the other set for recording the information digits. Apparatus for reading the code comprises two magnetic pick-up means synchronously rotatable about the tyre axis along a path adjacent the associated magnetizable member and active to develop electrical code pulses representing the digits. Pulse-translating means rotatable synchronously with and coupled to the pick-up means are coupled to a detector responsive to the indexing digits to actuate a timing-pulse developer emitting pulses at intervals equal to those between the pick-up of successive information digits of a correctly-coded tyre. A circuit receiving inputs from the timing-pulse developer and the pick-up means develops and stores on output representing the individual information digits on the magnetizable members. The read-off apparatus is such that the code can be read with the tyres the correct way up or inverted. The coded information may be used for inventory control and tyre sorting; information on several tyres may be decoded by machines at different locations, stored centrally, and scanned to control tyre sorting at the several machines.
